Unit testing a functions whose purposes is side effects
- by David
How would you unit test do_int_to_string_conversion?
#include <string>
#include <iostream>
void do_int_to_string_conversion(int i, std::string& s) {
switch(i) {
case 1:
s="1";
break;
case 2:
s="2";
break;
default:
s ="Nix";
}
std::cout << s << "\n";
}
int main(int argc, char** argv){
std::string little_s;
do_int_to_string_conversion(1, little_s);
do_int_to_string_conversion(2, little_s);
do_int_to_string_conversion(3, little_s);
}
